[OE-core] [PATCH] oeqa/oelib/path: don't leak temporary directories

[Ross Burton]

setUp() is used to populate a directory of temporary files, and deleted in
__del__.  However setUp() is called once *per test* so __del__ would only be
able to remove the last directory created.

Fix the code by using the natural counterpart to setUp, tearDown(), to clean up.
